Welsh scientists from Swansea University are investigating the feasibility of living and working in tall buildings that sway like trees in the wind. Traditional construction methods involve using large amounts of concrete and steel to minimize movement in tall buildings, leading to significant carbon emissions.
The research team, in collaboration with Cardiff University, the University of Exeter, and the University of Bath, aims to explore whether it is necessary for buildings to remain rigid or if a certain level of flexibility could be acceptable. Professor Ian Walker, an environmental psychologist at Swansea University, highlights that the majority of emissions from new buildings result from producing materials like concrete and steel.
According to Professor Alex Pavic from the University of Exeter, tall buildings are designed to withstand wind forces by using excessive materials that contribute to environmental impact. The project, called LOCAST (Low-Carbon Structures), funded by UKRI with £1.2 million, will investigate the possibility of reducing carbon footprints by allowing buildings to sway slightly.
Dr. Jennifer Davies, a physiologist from Cardiff University, suggests that people might adapt to building movement similar to how they tolerate motion on a swaying train. The research involves using a structural motion simulator to study the effects of building sway on occupants. By employing virtual reality technology, researchers will assess how structural movement impacts comfort, wellbeing, and productivity.
The findings of the study will be shared with the construction industry to promote the development of more sustainable and lightweight building practices worldwide. The aim is to challenge industry standards and potentially reduce the use of excessive materials in high-rise constructions. This innovative approach could revolutionise the design and construction of tall buildings, offering both environmental and economic benefits on a global scale.
